It provides declarative support for caching, validation, transactions and formatting. It provides powerful abstraction to JavaEE specifications such as JMS, JDBC, JPA and JTA. to assemble the dependencies between the objects. The main tasks performed by IoC container are: to instantiate the application class. The IoC container gets informations from the XML file and works accordingly. The Dependency Injection feature of Spring Framework and it support to various frameworks makes the easy development of JavaEE application. The IoC container is responsible to instantiate, configure and assemble the objects. The Spring Framework doesn't force the programmer to inherit any class or implement any interface. Spring framework is lightweight because of its POJO implementation. The EJB or Struts application require server to run the application but Spring framework doesn't require server. The Dependency Injection makes easier to test the application. The Spring applications are loosely coupled because of dependency injection. You need to write the code of executing query only. Let's take the example of JdbcTemplate, you don't need to write the code for exception handling, creating connection, creating statement, committing transaction, closing connection etc. It hides the basic steps of these technologies. So there is no need to write too much code. Spring framework provides templates for JDBC, Hibernate, JPA etc. They are as follows: 1) Predefined Templates There are many advantages of Spring Framework. makes the code loosely coupled so easy to maintain.We provide metadata to the IOC container either by XML file or annotation. In Spring framework, IOC container is responsible to inject the dependency. In such case, there is no need to modify the code if our logic is moved to new environment. Initializr generates spring boot project with just what you need to start quickly Initializr generates spring boot project with just what you need to start quickly Project. Thus, IOC makes the code loosely coupled. Let's understand this with the following code: They make the code easier to test and maintain. These are the design patterns that are used to remove dependency from the programming code. Inversion Of Control (IOC) and Dependency Injection Let's understand the IOC and Dependency Injection first. We will learn these modules in next page. The Spring framework comprises several modules such as IOC, AOP, DAO, Context, ORM, WEB MVC etc. The framework, in broader sense, can be defined as a structure where we find solution of the various technical problems. It can be thought of as a framework of frameworks because it provides support to various frameworks such as Struts, Hibernate, Tapestry, EJB, JSF, etc. Spring Tutorial For Beginners With Examples Edureka Spring IDE Installation Note: Before you start installing IDE, you need to have Java installed in your system.
